Abstract (en)

[origin: WO2019161927A1] A technique includes transmitting a request for the delivery of multicast data; receiving the multicast data via a unicast data radio bearer or a multicast data radio bearer, wherein the user device is located in a first cell; receiving, by the user device from the base station, a connection suspend message, wherein the connection suspend message includes: information describing a radio access network (RAN) multicast area (RMA) for the delivery of the multicast data via a multicast data radio bearer, and a group identifier associated with the multicast data, wherein the RMA includes a list of one or more cells that has been updated by the base station to include the first cell where the user device is located; entering, by the user device, a low activity state in response to the connection suspend message; and, receiving, by the user device, the multicast data via the multicast data radio bearer.
